cleopatra was known to have worn all of these gemstones except?

Answer 1

~Duh, in asking something like "all of these except", you are required to post a list from which the inappropriately placed item may may be redacted. I am resonably sure she didn't have any Zircon.

Answer 2

Cleopatra had emerald mines and her favourite stone has historically been quoted as peridot. She wore, and even ate, pearls but she did not have opals. It is said that Mark Antony tried to purchase an opal for her, but the seller fled the country before the deal was done.

Answer 3

I can name a lot she probably never even heard of, like jade, Dandrite, Tanzanite, and Australian or Mexican opals. They all come from areas she wouldn't have had any contact with.
